Hi!

I just ran into another regression with gcc on SuperH, this time while trying
to compile libav 11.2 on gcc-4.9.2:

/«PKGBUILDDIR»/libavcodec/dpxenc.c: In function 'encode_frame':
/«PKGBUILDDIR»/libavcodec/dpxenc.c:176:1: internal compiler error: in
elimination_costs_in_insn, at reload1.c:3638
 }
 ^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.9/README.Bugs> for instructions.
Preprocessed source stored into /tmp/cchMsw9Z.out file, please attach this to
your bugreport.
/«PKGBUILDDIR»/Makefile:44: recipe for target 'libavcodec/dpxenc.o' failed
make[1]: *** [libavcodec/dpxenc.o] Error 1

I am attaching the preproccesed source file cchMsw9Z.out to this bugreport.

Full log can be found in [1].

            Bug ID: 65152
           Summary: Several friend function definitions break lookup
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

When there is more than one class defining a friend function, name lookup fails
in the enclosing scope.

Live example: http://goo.gl/gwA3ej (also pasted at the bottom).

If either friend function definition at line 7 or 12 is commented out, the code
compiles and the call at line 18 correctly resolves to the global function.
However, with two friend functions defined the call results in compilation
error. The call is also resolved properly with the using declaration at line 17
uncommented, but this shouldn't be necessary since the friend functions
shouldn't alter the visibility of the global function and should only be
accessible via ADL.

The code:

void test(int);

namespace N {

struct A
{
  friend void test(A); // line 7
};

struct B
{
  friend void test(B); // line 12
};

void f()
{
  //using ::test;  // line 17
  test(0); // line 18
}

}
